<p><span title="" class="">Thanks</span>, Bill.</p>
<p><br>
</p>
<p>How about, for PVVT, is it possible to set a unique supply flow per cooling (or heating) stage? Could the hourly value of the COOL-STAGE keyword be used in a BDL expression to dictate SUPPLY-FLOW?</p>
<p><br>
</p>
<p>Thanks,</p>
<p>Phil </p>

<span style="font-size:11.0pt; font-family:"Calibri",sans-serif; color:#1F497D">No, not exactly. But you can specify different system MIN-FLOW-RATIOs for cooling mode and heating mode.</span></p>
<p style="margin:0in 0in 0.0001pt; font-size:12pt; font-family:"Times New Roman",serif">
<span style="font-size:11.0pt; font-family:"Calibri",sans-serif; color:#1F497D">For your example, you can set HMIN-FLOW-RATIO to 550/800 = 0.6875.</span></p>
<p style="margin:0in 0in 0.0001pt; font-size:12pt; font-family:"Times New Roman",serif">
<span style="font-size:11.0pt; font-family:"Calibri",sans-serif; color:#1F497D">You would also need to change the FAN-CONTROL to something other than CONSTANT-VOLUME for PSZ systems.</span></p>
<p style="margin:0in 0in 0.0001pt; font-size:12pt; font-family:"Times New Roman",serif">
<span style="font-size:11.0pt; font-family:"Calibri",sans-serif; color:#1F497D">For VAVS and PVAVS systems, you also have the option of specifying an HMAX-FLOW-RATIO, but not greater than 1.0.</span></p>
<p style="margin:0in 0in 0.0001pt; font-size:12pt; font-family:"Times New Roman",serif">
<span style="font-size:11.0pt; font-family:"Calibri",sans-serif; color:#1F497D">You can change these values at the zone level as well.</span></p>

<p><span style="font-family:"Calibri",sans-serif; color:black">With a PSZ or PVVT system type in eQUEST, is it possible to define a different supply airflow in heating vs cooling mode (ex. 800 CFM in cooling mode; 550 CFM in heating mode)? If so, how can this
be done? Thanks!</span></p>
